J2EE搭建云服务器

---

JDK 安装

---

1. 查看当前云服务器系统版本信息

```bash
    uname -a
```

2. 下载并安装JDK

[Oracle官网JDK下载链接](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)

```bash
    wget http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.tar.gz?AuthParam=1504343731_c3e116a1d6b955e51a473f423afebb8b
```
